Breaking changes
editThe following changes in Elasticsearch 8.7 might affect your applications and prevent them from operating normally. Before upgrading to 8.7, review these changes and take the described steps to mitigate the impact.
There are no notable breaking changes in Elasticsearch 8.7. But there are some less critical breaking changes.
Ingest changes
editMaking JsonProcessor stricter so that it does not silently drop data
Details
The ingest node’s json processor was previously lenient. It would accept invalid JSON data if it started with valid JSON data.
Anything after the valid part would be silently discarded. From 8.7 onwards, the default behavior is to reject invalid JSON data with
an exception so that data is not silently lost. The old behavior can be reproduced by passing false as the value of the new
strict_json_parsing processor parameter.
We consider this change to be a bugfix but list it here as a breaking change since it may affect the behavior of applications which
were sending invalid JSON data to the json processor.
Impact
Ensure your application only sends valid JSON data to the json processor, or modify the json processors in your pipelines to set
the strict_json_parsing parameter to false.
